This application is a continuation, of application Ser. No. 111,908, filed Jan. 14, 1980 and now abandoned.
The present invention relates generally to improvements in devices and methods for the personal identification of a client at a subscriber location, but more particularly, it relates in one respect to improvements in personal identification methods practiced without use of cards or other devices which must be carried by the client and are thus subject to loss, theft or compromise.
In some respects, the present invention, may be considered as a continuation in part of my co-pending application for United States Letters Patent Ser. No. 762,299 filed Jan. 25, 1977, now U.S. Pat. No. 4,184,148.
In the co-pending application, there are disclosed identification devices and methods which include simple grids and the concept of personal identification by means of positional codes to determine the correct digits for proving identity in response to the presentation to the client of any of a plurality of like grids. The devices and methods of the application, however, have suffered from two principal shortcomings. One of these is that in order to avoid making the grid excessively complex, it has been necessary that their size in terms of the number of digits, which they contain, be limited. The result is that there is a remote possibility, however slight, that a client's positional code might be discovered by a trial and error process carried out over a lengthy and tedious period of time by a determined impostor. A more important problem is the difficulty which clients have experienced in remembering their positional codes. Even though the application proposes an overlay of an object to aid the client's memory, there has generally been a tendency to forget.
It is accordingly an object of the present invention to improve the security of identification devices and methods.
At the same time while the security is being improved, it is a further object to assist the client to remember the positional codes which will establish his identity.
In the achievement of the foregoing objects, a feature of the invention relates to a new form of grid in which numerals are arranged in a pattern around letters of the alphabet which establish the positions. The letters may be arranged either alphabetically or alternatively in the pattern employed in a typewriter keyboard with which many clients are already familiar.
Another feature relates to a check form in which a grid is displayed on the back of the check and may be used for the purpose of identifying the maker of the check who would have his check cashed in a location where he is not personally known. Identification of the maker may be readily established by receiving from him an independent identification number together with the check number and four identifying digits. The identity may then be verified by telephoning a central bureau and communicating the information received from the potential check casher, to be verified against a register.
The foregoing objects and features, together with numerous advantages to be derived from the invention will be more fully understood and appreciated from the following detailed description of illustrative embodiments taken in connection with the accompanying drawings in which:
FIGS. 1 and 2 are drawings of alternative grid formats employed in the practice of the present identification methods;
FIG. 3 is a drawing depicting the front face of a check intended to be used in conjunction with the identification methods of the present invention;
FIG. 4 is a view depicting a grid format appearing on the back of the check of FIG. 3 and an arrangement of letters different from the grids depicted in FIGS. 1 and 2;
FIG. 5 is an alternative grid arrangement similar to FIG. 4 but including different digits; and
FIG. 6 is a fragmentary view depicting a form of register used in the practice of the present invention.
Turning now to the drawings, particularly FIGS. 1 and 2, there are shown grids including letters arranged in three rows and in alphabetical order. Arranged in a pattern around each letter of the alphabet are four digits above, to the right, below and to the left of each letter. For purposes of simplicity, the location of any digit relating to a letter is given as UP, DN for down, R for right and L for left. Thus, as seen in FIG. 1 A-UP is 6, A-DN is 4, A-R is 5 and A-L is 9.
For remembering his positional code, a client may be given the word HOME UP and this would also be entered in the register as seen in FIG. 6. When the client whose identification independently provided could be 035-12-6983 is presented at a subscriber location with the grid depicted in FIG. 1, numbered 6549 after the digits surrounding the letter in the upper left hand corner of the grid, the A, his response is 6178. On the other hand if presented with the grid depicted in FIG. 2 simiarly numbered for 9478 his answer should be 7544. If the same client intends to cash a check no. 277, (as shown in FIG. 3), he will refer to the grid format on the reverse side of the check No. 277 as shown in FIG. 4, in which the letters are arranged in the order found on a typewriter keyboard, and the client's answer should be 1934. If the check to be cashed had the grid depicted in FIG. 5, that on the back of check number 278, his answer should be 5782. If a second client having an independent identification of 035-12-6984 and the password JOHN DN his answer when presented with grid number 6549 of FIG. 1, should be 4742 while his answer when presented with grid number 9478 of FIG. 2, should be 4212. If the second client should wish to cash check 277, he would refer to the grid appearing on the back of this check and depicted in FIG. 4 and give the answer 6357, but if the check were number 278, he would refer to the grid in FIG. 5, which is printed on the back of that check and give the answer 5936.
From an inspection of FIGS. 1 and 2, for example, it is obvious that all twenty-six letters of the alphabet are displayed in each grid and that some or all of the digits from 0 to 9 are correlated in each direction around the letters. Thus, assuming that all the letters and all the digits are used in each direction in each grid, a predetermined ratio is thereby established. Accordingly, considering only the down direction, for example, the digits are repeated several times on average in each direction of each grid, this repetition rate, which increases the difficulty of deciphering a client's code by an outsider, is subject to being reduced if some letters are eliminated and increased if some digits are not used.
